Keeping pets safe in travel trailer while “home alone”

An ignorant course of action. We watched 5 different folks warned in one weekend by rangers for leaving dogs behind which disturbed others in a VA state park, 3 of whom did not heed the warning and were made to vacate Saturday evening.

RVs are not even close to soundproof and every place we've ever been had either a solid rule against the practice or a generic rule that you can not disturb others. But then again, little Precious never barks.
